Abstract: Underwater power apparatus for harnessing a flowing river or large stream, includes blades or sails moving within a housing and in a circuit on a power leg and return leg. The housing directs the stream flow onto the power leg to drive the apparatus and diverts the flow from the return leg to provide a quiescent area for the return leg. Preferably, the blades or sails are opened when on the power leg and are folded or closed when on the return leg to reduce resistance. The underwater power apparatus may have either arcuate or linear power and return legs. In the latter case, the legs can be of sufficient length to develop a high power output. Since the apparatus is disposed completely underwater it disrupts neither the scenic beauty nor the navigation of the river.

Abstract: An exhaust gas processing device for use with internal combustion engines is disclosed which is generally of the afterburner type, including a cylindrical reactor in which unburned carbon monoxide (CO) and hydrocarbons are consumed and an exhaust pipe connected near one end of the cylindrical reactor in such manner as to direct the flow of gases tangentially into the reactor to produce a vortical flow pattern. Additional air for combustion is supplied by means of an engine-driven air pump, and this air flow is also directed into the reactor chamber in a manner to produce a vortical flow pattern which is combined with the vortical flow of exhaust gases. An ignition device such as a spark plug is supplied at the upstream end of the reactor chamber to assure ignition of the exhaust gas mixture. Flame propagation is maintained through the use of annular internal baffles or flame holders exposed to the ignited gases and which become very hot and operate somewhat similarly to glow plugs.

Abstract: A thermal reactor for an internal combustion engine wherein when the temperature of the engine is low, exhaust gas exhausted from the engine is reacted in an inner core before it is mixed with secondary air and then guided to a riser member where it is heat-exchanged with intake gas mixture and thereafter exhausted through a bypass passage, and when the temperature of the engine is moderate to high the exhaust gas is mixed in the inner core with the secondary air introduced into the inner core through the vicinity of the riser member, whereby unburnt component in the exhaust gas is burnt and exhausted.

Abstract: A combustion liner for a gas turbine combustion apparatus is composed of a series of ceramic wall rings coaxially aligned from the upstream to the downstream end of the liner. The ceramic rings are connected so as to be free to expand radially relative to each other while maintaining alignment. One type of connection between the rings involves notches distributed around the ends of a ring and bosses distributed around the adjacent end of the next ring entering into the notches. Another type of interconnection involves notches distributed around adjacent ends of two ceramic rings with a metal ring disposed between them having bosses which engage in some of the notches to align the parts. The liner is supported by supports at the ends of the liner from an outer casing. One support includes a spring to accommodate relative expansion of the liner and outer casing.
